Acute Care Hospitalization Rate
The acute care hospitalization (ACH) rate is the percentage of home health stays during which the patient was admitted to an acute care hospital, historically measured over the first 60 days of home health. It is a claims-based, risk-adjusted measure that served for years as the industry's headline utilization metric before CMS began shifting to the Potentially Preventable Hospitalization measure.
